' Application mea may 2, I1901. serial No. 371,491.

To all whom t't-may concern:

Be it known that I, HENRY of Battle Creek, inthe county of .Calhoun andState of- Michigan, have invented certain new and useful IImprovementsin Folding Mechanisms for Web-Printing Presses; and I hereby declarethat the followin is a full, clear, and exact description thereof,reference being had to the accompanying drawings, which form part ofthis specification.

This invention 1Sl an improvement in folding mechanisms for newspaperweb-printing presses, and its object is to provide means whereby sheetsmay be directed either from the second-fold rolls to the stacker to bedelivered folded half-size, or may be passed on to the third-fold rollsand be deliveredv folded one-fourth size; and for this purpose I providea series of tapes which may be adjusted into different positions, so astov either direct the papers from the secondfold rolls to the'third-fold rolls; or permit them to pass direct from the second-foldrolls to the stacker.

The invention consists in the novel arrangement of such tapes and meansfor adjusting them as will be fully understoodfrom the followingdescription in connection with the drawings, in which- Figure 1 is adiagrammatical sectional elevation of the folding mechanism of aweb-printing press; and Fig. 2 is an end elevation of Fig. 1 partlybroken awa Thefolding mechanism is provide as usual, with first-foldrolls 1, 1a (located at the apex of the former F over which the web isled from the press to the first-fold rolls,)-

by which the web -is folded longitudinally upon itself before it issevered. It is then passed between the cutting cylinder 2 and thefolding cylinder 2a, which may be 'provided with tuckers, indicated atT, constructed as usual so that if desired two or more sheets may becollected upon cylinder 2a before they'v are passed into the secondfoldrolls 3, 3a. After lthe desired number` of sheets have been severed andcollected upon cylinder 2, they are discharged from said cylinder, -bythe'well known means and in the well known manner, between thesecond-fold rolls 3, 3, by which the severed sheets are foldedtransversely upon themselves to half-size papers.

At one side of the second-fold rolls are third-fold rolls 8, whichusually are yar- F BECHMAN,

i which the one halffold papers can readily change the folder ranged atright angles to rolls 3, 3*?, andthe papers may be directed from thesecond-fold rolls to the third-fold rolls by the following means: j

The roll 3 is provided with tape-channels at intervals in its face, inwhich channels are guided tapes 6 which, as shown-in full lines in Fig.1, run between rolls 3, 3, to and over pulleys 5 on stub shafts 5caffixed to arms 5d mounted on-a fixedv shaft 5e. The tapes 6 pass frompulleys 5 to and over adjustable pulleys 6a mounted on stub shafts 6battached to brackets 6c adj ustably mounted on rods 6e attached to afixed shaft 6. The brackets 6c are adjustable on rod 6e and .may befixed in position thereon by bolts 6d von brackets 6.

On stub shaft 5 beside pulleys 5a, are pulleys 5 over which run tapes 7which are adapted to convey the paper to and over the third-fold rolls 8and under tucker blade 8, which is arranged to be operated in the usualmanner so as to pass the papers between the third-fold rolls wherebythey are folded to one-quarter size. When the tapes 6 are in theAposition describediand shown in full lines Fig. 1, the sheets will bedirected by said tapes 6 onto tapes 7 and carried by the latter to andover third-fold rolls 8.

If the tapes 6 are adjusted to the position shown in dotted lines inFig. 1, the papers can pass from the second-fold rolls 3, 3a, in frontof upright fingers 4 behind which is located a shaft 4b carrying rotaryflies 4 by be stacked in the usual manner.

' If it is not desired to have the papers folded to one-quarter-size,the tapes 6 are slipped off of pulleys 5a and the pulleys 6a are movedback lo n rods 6e to the position indicated in dotted lines in Fig. l,and when tapes 6. are in such position'the papers will drop from the`second-fold rolls 3, 3a, in front of thefrotary ily 4a. By means ofthese tapes 6 ltherefore the operator can to produce papers foldedeither to half-size or quarter-size, and when running quarter-size-foldpapers there is nochance for the papers to become fouled with the rotaryfly, or the fingers 4 as the tapes 6 carry the papers positively aroundand under roll 3a to the tapes 7, and the papers do not have to jump anyspaces between tapes or rollers in 'order to reach the third-fold rolls.

Having described my invention what I llO ing device; adjustab e claim asnew and desire to secure by Letters Patent is:

l. In a folding mechanism, the combination of a-pair of folding rolls,means for directing papers/thereto; a second pair vof folding rolls atright angles to the first fold rolls, and means for carrying papersthereto; with tapes extending between the rst pair of folding rolls,and'nieans whereby said tapes can be adjusted either to direct thepapers from the first pair 'of folding rolls to the second pair offolding rolls, or to permit the papers to be discharged away from therst pair of folding rolls.

2. In a folding mechanism, the combination of cutting and collectingcylinders, a pair of folding-rolls adjacent thereto, a second foldingdevice adjacent the folding rolls, a stacker beneath the folding rolls,and an adjustable set of tapes extending between` the folding rolls,andl adapted when in one position to permit the papers to pass direct tothe stacker; and in the other position to direct the papers onto thesecond folding devices.

3. In a folding mechanism, the combination of cutting and collectingcylinders, a ,pair of folding rolls adjacent thereto, a second setoffolding rolls adjacent the first folding rolls; a rotary fly vbeneaththe first folding rolls, and an adjustable set of tapes extendingbetween the first pair of folding rolls, andadapted in one position topermit lthe papers to pass direct to the rotary fly;

and 1n t-he other position to direct the papers onto the second set offolding rolls.

4:. -The combination with a pair of foldin rolls, a second foldingdevice adjacent sai rolls, a stacking device below said rolls, tapes forcarrying pa ers to the second foldtapes extending between the foldingrolls, relatively stationary pulleys for said tapes below the foldingrolls, and adjustable pulleys for said tapes at one side of such rolls,whereby said tapes can be adjusted to permit papers to pass direct tothe stacking device or on to the second folding device.

5. The combination in a folding mechanism, of a former, a pair offirst-fold rolls at its apex, cutting cylinders adjacent said first-foldrolls; a pair of second-fold rolls; a set of third-fold rolls adjacentthe secondfold rolls, and a` stacker below the secondfold rolls; with anadjustable set of tapes extending between the second-fold rolls, and ifixed and adjustable guide pulleys for said tapes, whereby said tapescan be adjusted either to direct papers from the second-fold rolls tothe third-fold rolls, or to permit the papers to pass direct from thesecond-fold rolls to the stacker.

6. The combination in a folding mechanism, of a former, a pair offolding rolls at its apex, cutting and collecting cylinders adjacentsaid folding rolls; a pair of secondfold'rolls, adjacent the collectingcylinder; a set of third-fold rolls adjacent the secondfold rolls, and arotary fly stacker below the second-foldrolls; with an adjustable set oftapes extending between the secondfold rolls, and fixed and adjustableguide pulleys for said tapes, whereby said tapes can be adjusted eitherto direct papers from the second-fold rolls to lthe third-fold rolls, ordirect from the second-fold rolls to the rotary fly stacker,substantially as described.

In testimony that I claim the foregoing as my own, I affix my signaturein presence of two witnesses. i
